I was diagnosed last June of stage two cancer in my right tonsil which had spread to the lymph glands in my neck. I've completed my treatment and thankfully go the all clear in a January. I know that thick saliva is a side effect and can take anything up to two years to settle. I've noticed recently that it has a salty taste. Is this common. I tried to ask at the hospital on my last check up but the doctor was very non comital.
